Ultrasensitive colorimetric DNA detection using a combination of rolling circle amplification and nicking endonuclease-assisted nanoparticle amplification (NEANA).
A combination of rolling circle amplification and nicking endonuclease-assisted nanoparticle amplification (NEANA) is used for the rapid, colorimetric detection of DNA. The integration of rolling circle amplification into the NEANA approach allows for detection of oligonucleotides with arbitrary sequences at ultralow concentrations.
متن کاملA Novel Ultrasensitive ECL Sensor for DNA Detection Based on Nicking Endonuclease-Assisted Target Recycling Amplification, Rolling Circle Amplification and Hemin/G-Quadruplex
In this study, we describe a novel universal and highly sensitive strategy for the electrochemiluminescent (ECL) detection of sequence specific DNA at the aM level based on Nt.BbvCI (a nicking endonuclease)-assisted target recycling amplification (TRA), rolling circle amplification (RCA) and hemin/G-quadruplex. The target DNAs can hybridize with self-assembled capture probes and assistant probe...
متن کاملSignal amplification by rolling circle amplification on DNA microarrays.
While microarrays hold considerable promise in large-scale biology on account of their massively parallel analytical nature, there is a need for compatible signal amplification procedures to increase sensitivity without loss of multiplexing. Rolling circle amplification (RCA) is a molecular amplification method with the unique property of product localization. This report describes the applicat...
متن کاملRolling Circle Amplification (RCA): an approach for quick detection and identification of fungal species
Conventional methods for fungal identification in the clinical laboratory rely on morphological andphysiological tests. These tests often need several days or weeks to complete and are frequentlyunspecific. Molecular identification mostly implies sequencing, which is relatively expensive andtime-consuming, as well as impractical for large numbers of isolates. The Rolling CircleAmplification app...
متن کاملNicking enzyme based homogeneous aptasensors for amplification detection of protein.
A simple and highly sensitive homogeneous aptasensor is developed, which relies on nicking enzyme. The sensitivity of this newly proposed aptasensor is about three orders of magnitude higher than that of traditional homogeneous aptasensors. Furthermore, it is capable of detecting target protein in real samples.
